This is a preliminary list of vsock patches we have in Linux 6.4-rc4 that we should backport into RHEL-9.3: 6d4486efe9c6 vsock: avoid to close connected socket after the timeout eaaa4e923979 vsock/loopback: don't disable irqs for queue access b5d54eb5899a vsock/test: update expected return values 02ab696febab vsock: return errors other than -ENOMEM to socket f59f3006ca7b vsock/vmci: convert VMCI error code to -ENOMEM on receive ffa5395a7901 vsock/vmci: convert VMCI error code to -ENOMEM on send f9d2b1e146e0 virtio/vsock: fix leaks due to missing skb owner 25209a3209ec test/vsock: new skbuff appending test b8d2f61fdf2a virtio/vsock: WARN_ONCE() for invalid state of socket f7154d967bc4 virtio/vsock: fix header length on skb merging d61bd8c1fd02 selftests/bpf: add a test case for vsock sockmap c7c605c982d6 selftests/bpf: add vsock to vmtest.sh 634f1a7110b4 vsock: support sockmap 24265c2c91ad testing/vsock: add vsock_perf to gitignore e3ec366eb0d1 virtio/vsock: check argument to avoid no effect call b68ffb1b3bee virtio/vsock: allocate multiple skbuffs on tx b465518dc27d vsock/loopback: use only sk_buff_head.lock to protect the packet queue 4d1f51551777 virtio/vsock: check transport before skb allocation 7e699d2a4e81 test/vsock: copy to user failure test 8daaf39f7f6e virtio/vsock: don't drop skbuff on copy failure 6825e6b4f8e5 virtio/vsock: remove redundant 'skb_pull()' call 077706165717 virtio/vsock: don't use skbuff state to account credit 759aba1e6e7d vhost: remove unused paramete 71dc9ec9ac7d virtio/vsock: replace virtio_vsock_pkt with sk_buff 8abbffd27ced test/vsock: vsock_perf utility 685a21c314a8 test/vsock: add big message test 5c338112e48a test/vsock: rework message bounds test c43170b7e157 vsock: return errors other than -ENOMEM to socket New features: - replaced virtio_vsock_pkt with sk_buff to allow new features and improve performance (usual test can be used) - supported sockmap (new tests included) - returned better error on send()/recv() failure (tests updated)
I'll remove sockmap support from the backport since there are several conflicts and it is still not well tested upstream.
